A Three Dimensional Method for Gamut Mapping
Abstract:It is necessary to ensure that the color reproduction of an original will offer a good correspondence between the original and reproduction gamut. The transformation of the gamut of input device to fit that of output device is called gamut mapping. It is very important to decide the mapping direction considering three attributes of color i.e. hue, lightness and chroma. The mapping directions can be categorized as one, two or three-dimensional. Considering some limitations of one or two-dimensional models, a threedimensional gamut mapping is suggested in the present study. The experimental results show that the clipping or compression do not have similar effects if the images vary from low-key to high-key ends. The compression method also depends on image quality. In the present study, threedimensional gamut mapping has been adopted for different image qualities to indicate the preferred method.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
